Debug and troubleshoot embedded systems using tools such as GDB, JTAG, and logic analyzers
Participate in customer engagements to gather requirements and usability criteria

Our take

Neural networks and CPUs are vital to AI solutions, but manufacturers have largely failed to maintain innovation in recent years. Lightmatter solves this problem by offering a next-generation computing platform powered by photonics (light waves).

Lightmatter offers a forward-facing platform for AI-building that acts as an alternative to traditional solutions. It works by replacing wired CPUs with a combination of photonics and new algorithms. Lightmatter's solution is not only faster, but it is considerably more sustainable, and it has the potential to drive the next generation of AI development.

As of early 2026, Lightmatter had raised $850 million across six funding rounds and grown to a staggering valuation of $4.4 billion. This showcases the growing demand for faster, more effective AI-building solutions. With products already on the market and a roadmap to tackle even more components in the years ahead, the future for Lightmatter certainly looks bright.
